Wow that would be great! The high number of casualties during the 2002 tsunami mostly was due to a lack of early alerting, as not enough tsunami buoys were deployed. This could have save so many lives.
Many areas that suffered the waves had earlier felt the earthquake that caused it (including here in India) and the sea receded in some places. Almost no one was alarmed by this or understood what was to follow. Even the news media didn't initially understand what they were reporting.
That situation has changed now. Sufficient buoys are deployed along with public warning systems. People are also much more sensitive to the warning signs. I don't think anybody will be caught by surprise like that in the future. That said, any new concepts and advancements are welcome. The more the merrier.
PS: We're coming up on the 20th anniversary of that disaster - the 26th of this month. Please remember the more than 128K people that perished on that day. Some of them were younger than much of the HN audience. May the victims and the lessons of that day never be forgotten.
